Submersible electric pumps in aisi 904 stainless steel and mixed flow duplex

About Submersible Pumps for Drilling

Pegasus 6”, 8” submersible borehole pumps are radial flow and mixed flow, high efficiency, to perform perfectly at the point of service



Semi-axial submersible electric pumps in aisi 904 stainless steel. The stainless steel structure with the external jacket, guarantees the permanent alignment of all the components and with the floating wear rings in PTFE, the ceramic guide bushings and the bearings. rubber grooves give the pump more resistance over time. This range of submersible pumps for boreholes has been designed to guarantee high efficiency by reducing energy consumption and therefore costs.
